Along with nearest recording equipment provides improved image quality, requirement can be at the enterprising line item of various recording mediums day by day.As an example, requirement can carry out on the surface ink mist recording as CD (CD) or the DVD enterprising line items of disc recording medium (being hereinafter referred to as " discoid medium ") such as (Digital video discs).Discoid medium has and the ink mist recording face original data recording surface of antidirection finding mutually.Data recording surface is damaged from the outside easily.Thereby because possible damage, discoid medium can not be arranged in the recording equipment independently.Therefore, need on the carrier that uses purpose-made pallet, carry discoid medium basically.In addition, developed special recording medium in recent years with shape identical with the shape of carrier.In order to carry out record, can pile up this recording medium on the guiding piece that purpose-made pallet is arranged piling up.
The rigidity of discoid medium and purpose-made pallet is such as the rigidity height of sheet materials such as paper.Thereby, be difficult to from automatic paper feeder (being hereinafter referred to as " ASF ") feeding discoid medium; This automatic paper feeder when making the sheet material bending with arbitrarily angled feeding sheet material, rather than with respect to conveying roller feeding sheet material flatly.Thereby the recording equipment that is used for discoid medium comprises special-purpose supply port.Usually, in order to simplify user operation, be provided with through the front side of the recording equipment of being everlasting discoid medium special-purpose supply port.In addition, in order to reduce the size of recording equipment, with discoid medium the special-purpose pallet guiding piece that is directed to supply port have two positions usually, promptly supply with position and collecting position, rather than always be positioned at and supply with the position.
In this recording equipment, for the detection error that reduces to cause by swing attached to sheet material on the bar or bar, following structure PE rodmeter (paper end detecting sensor bar).That is to say that the shape on the top of bar and position are configured to form acute angle along the abutting part of sheet material throughput direction and sheet material.Usually the angle of PE rodmeter is set in consideration from the direction of feed of the sheet material of ASF.When the PE rodmeter was arranged in the discoid medium transport path, if pallet is inserted through the aforesaid supply port that only is used for discoid medium that is formed on the front of recording equipment, then pallet may be interfered with the PE rodmeter.Thereby, may damage the PE rodmeter.
Thereby in conventional art, as Fig. 8 and shown in Figure 9, PE rodmeter (paper end detecting sensor bar) 321 leaves the location, transport path ground that is used for the discoid medium pallet, interferes to prevent pallet and PE rodmeter 321.
In Fig. 8 and Fig. 9, the first sheet material A is the recording medium with minimum width dimension that can carry from the ASF (not shown) of recording equipment.The second sheet material B is the recording medium with greatest width dimension that can carry from the ASF of recording equipment.Feed rolls 28 is stacked on sheet material on the ASF to the record portion feeding of recording equipment.Roller rubber 281 is installed on the part of feed rolls 28.PE sensor 32 is installed to the frame (not shown).PE rodmeter 321 covers and opens the light receiver and the light emission part of sensor, so can detect the end of sheet material.Conveying roller 36 forms roll gap portion with the pinch roll 37 that is subjected to bias voltage from the top, with conveying recording medium.The downstream along recording medium transporting direction that the balladeur train 5 of record head is installed thereon is provided with distributing roller 40.Distributing roller 40 forms roll gap portion together with relative ratchet (not shown), to carry the rear end recording medium by the roll gap portion that formed by conveying roller 36 and pinch roll 37, this recording medium is discharged to the outside of recording equipment.Tray guides 1001 from the place ahead of recording equipment to the inside of main body feeding discoid medium special-purpose pallet 1003.The shape of pallet 1003 is formed with discoid medium 1002 and engages, and pallet 1003 comprises the reflecting plate 1004 that is positioned on its end face, to detect the position of pallet 1003.As Fig. 8 and shown in Figure 9, the end of test section of PE rodmeter 321 (bar portion) and pallet 1003 is configured to set in the dimensional tolerance of considering parts and under the situation of the possibility that pallet 1003 tilts a little during carrying any distance dL between test section and end.
As another conventional example, following structure has been proposed: utilize the motor castle special use or that also be used for other driving purposes or solenoid that the PE rodmeter is kept out of the way from the recording medium transport path.Figure 10 is the stereogram that the structure of this conventional example is shown.As shown in figure 10, pinch roll 37 is relative with the conveying roller (not shown), with clamping and feeding sheets.Pinch roll keeper 30 keeps pinch roll.Represent the PE rodmeter with Reference numeral 321.Lift cam 1011 makes pinch roll keeper and P E rodmeter keep out of the way scheduled volume from transport path.Promoting gear 1012 combines coaxially with cam 1011.Represent intermediate calender rolls and box conveying motor with Reference numeral 86 and 85 respectively.In addition, represent a plurality of driven wheel row and planetary gear row with Reference numeral 851 and 852 respectively.Intermediate calender rolls 86 will be transported to record portion from the recording medium of the box (not shown) feeding on the bottom surface that is positioned at recording equipment.
Figure 11 A to Figure 11 C is the schematic cross sectional views of keeping out of the way operation that illustrates in the conventional construction shown in Figure 10.
